I'm sorry, but I can not completely answer this question. The length varies from the size of the triangle. I would need a picture to answer this.

If a triangle with a perimeter of 24 cm is an equilateral triangle, then each of its 3 sides will be 8 cm in length

They could be 3 cm by 4 cm by 5 cm for a right angle triangle.

The length of the hypotenuse of a right triangle with a 13 cm base and a 6 cm height is 14.32 cm

ABC is an equilateral triangle with side length equal to 50 cm. BH is perpendicular to AC. MN is parallel to AC. Find the area of triangle BMN if the length of MN is equal to 12 cm.

Use Pythagoras to find the perpendicular height of the triangle: 132-52 = 144 and the square root of this is the height of the triangle which is 12 cm Area = 1/2*12*10 = 60 square cm

The length of the hypotenuse of a right triangle with legs of 7 cm and 24 cm is: 25 cm

It is: 11.5 cm because 0.5*11.5*16 = 92 square cm

If it's a right angle triangle then using Pythagoras' theorem then the length of the hypotenuse is about 44.65422712 cm

The area of a triangle cannot be determined by its length and withgt or width, even. You need the length and the perpendicular height.

The length of the hypotenuse is: 44.65 cm

Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.

Yes.

It would be the square root 32 in cm
